Direct manipulation of checked

The checked attribute of an Checkbox object should always be set
through the Ember object or by interacting with its rendered element
representation via the mouse, keyboard, or touch. Updating the value of the
checkbox via jQuery will result in the checked value of the object and its
element losing synchronization.

Layout and LayoutName properties

Because HTML input elements are self closing layout and layoutName
properties will not be applied.
